Measuring Density

1-1 Measuring Density Background All matter has mass and volume. Mass is a measure of the amount of matter an object has. Its measure is usually given in grams (g) or kilograms (kg). Volume is the amount of space an object occupies. There are numerous units for volume including liters (l), meters cubed (m3), and gallons (gal). Mass and volume are physical properties of matter and may vary with different objects. For example, it is possible for two pieces of metal to be made out of the same material yet for one piece to be bigger than the other. If the first piece of metal is twice as large as the second, then you would expect that this piece is also twice as heavy (or have twice the mass) as the first. If both pieces of metal are made of the same material the ratio of the mass and volume will be the same. We define Density ( ) as the ratio of the mass of an object to the volume it occupies. The equation is given by: VM= ( ) here the symbol M stands for the mass of the object, and V the volume.

1-2 Activity 1: (Determine the density of an object with a regular shape.) Obtain a set of objects (cube, cylinder, sphere, etc.) made of the same material. Calculate the density by measuring the mass and volume of your samples.
